Behavior of basal respiration of a soil under restored forest, in Guantánamo

Abstract

In a restored forest there are factors that affect the health of a soil, such as biological factors and basal respiration. The research was carried out in the period from April 2021 to April 2023, in an area of ​​the Veriade farm, of the Cajobabo forestry UEB, Imías municipality, Guantánamo province, on an alluvial soil, of the evergreen gallery forest. Basal respiration was determined using the closed medium incubation method described by Anderson (1993). Soil samples were taken randomly in the years 2021, 2022 and 2023. The results obtained showed a tendency towards increased carbon dioxide (CO2) flow in the soil, a decrease in pH from acid to neutral, an increase in organic matter (OM) and an increase in respiratory activity, evidencing the presence of microorganisms in the area that favor plant growth.
